Effect of Head Height on the Penetration Efficiency of the Jet Formed by the Double Cone Liner

Popis výsledku v původním jazyce

This paper investigates the influence of head height on the penetration efficiency of a jet formed by a double cone liner in a newly designed shaped charge for a small-caliber warhead. Numerical simulations were conducted using the ANSYS AUTODYN 2D platform to analyze jet formation and penetration into a monolithic steel target. Different cases of head height, corresponding to head height to charge diameter ratios from 0.1 to 0.6, were selected for the study. Results show that penetration depth increases as head height rises, reaching a maximum at a head height to diameter ratio of 0.3. Exceeding this value, penetration depth does not improve despite the increase in jet kinetic energy and tip velocity. The results of this study provide a basis for evaluating and selecting an appropriate head height for shaped charge using a double cone liner, contributing to the optimization of shaped charge structural design to enhance penetration performance.
